Benefits of technology

[0006]The object of the present invention is to overcome the previous drawback by proposing a motorized trunk-closing system which is very simple to use.

Problems solved by technology

The drawback of such a system lies principally in the fact that it is necessary for the user always to have a hand free to manipulate the electric switch and thus operate the closing of the trunk.
Now, if the user is removing bulky and / or heavy objects from his trunk, it can be difficult for him, on the one hand, to access the switch and, on the other hand, to actuate it.

first embodiment

[0015] represented in FIG. 1, the trip device comprise a presence sensor 5 positioned level with one of the stays 4a connecting the trunk 2 to the trunk lid 3. The sensor is linked by an electrical connection (not represented) to the control unit. Preferably, the presence sensor is positioned on the inner side of the stay, facing the other stay. The user, even with arms laden, can thereby pass close to the sensor, within its detection zone, in an almost natural movement of removing objects from the interior of the trunk. The sensor then detects the presence of the user and sends a detection message to the control unit, which, in turn, operates the motor for the closing of the trunk. The stays are advantageously made of a nonmetallic material, such that they do not disturb the electromagnetic field level with the sensor.

[0016]Other places situated inside the trunk can be chosen for the positioning of the sensor:

second embodiment

[0017]In the invention illustrated in FIG. 2, the presence sensor is fixed directly, for example by gluing, onto an indicator device 6 fitted to the automotive vehicle 1. This indicator device traditionally contains a housing 6a enclosing the various optical and electrical components by which the traditional indicator functions can be realized, and a glass 6b sealing this housing. More precisely, the sensor 5 is fixed on a part of the indicator device, this part not being visible from the outside of the vehicle when the trunk lid 3 is in its second, closing position.

[0018]Advantageously, a lateral part of the device, situated inside the trunk, as represented in FIG. 2, is chosen, such that the detection zone of the sensor is included within the passing zone of the user when the latter comes to deposit objects or remove them from his trunk. In addition, the part should preferably be made of a non-metallic material so as not to interfere with the electromagnetic field of the sensor 5....

Abstract

The subject of the present invention is a motorized trunk-closing system for an automotive vehicle (1) comprising a trunk (2) having an interior and an operating mechanism for operating an automatic movement of a trunk lid (3) from a first position, in which the interior of the trunk (2) is accessible for a user, to a second position, in which the interior of the trunk (2) is shut off by said trunk lid (3), said operating mechanism comprising a trip device (5) placed level with the trunk in such a way as to be inaccessible from the outside of the automotive vehicle when the trunk lid (3) is in the second position. The trip device comprises at least one sensor (5) for detecting the presence of the user.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The subject of the present invention is a motorized trunk-closing system for an automotive vehicle.[0003]2. Description of Prior Art[0004]Trunk-closing systems are already known in which the movement of the trunk lid of a vehicle trunk from an opening position, in which the interior of the trunk is accessible to the user, to a closing position, in which the interior of the trunk is shut off by the lid, is operated automatically by means of a motorized mechanism. The motorized mechanism is itself operated by an electric switch by which the motor can be switched on. Such a system is described, for example, in U.S. Pat. No. 6,185,868.[0005]The drawback of such a system lies principally in the fact that it is necessary for the user always to have a hand free to manipulate the electric switch and thus operate the closing of the trunk. Now, if the user is removing bulky and / or heavy objects from his trunk, it can be difficult...
